Joe Biden just massively insulted black Trump supporters, after telling a popular black radio host on Friday that he 'ain't black' if he was still weighing whether to support Biden or Trump in the November election.

WHAT IF DONALD TRUMP HAD SAID THIS? Will Joe Biden get a pass on this??? I had to watch 3 times to make sure I actually heard what he said. Here it is verbatim: “if you have a problem figuring out if you’re for me or Trump, then YOU AIN’T BLACK” 😳🤯 https://t.co/h7xOwMecA0

Biden's comment came during an interview with "The Breakfast Club" host Charlamagne tha God, who challenged the former VP over his decades-long record on racial issues and asked him about possibly choosing a black, female running mate, according to Politico.

"I’m not acknowledging anybody who is being considered, but I guarantee you, there are multiple black women being considered. Multiple," said Biden of his (handler's) search for a VP nominee.

It was then that an aide to the Biden campaign could be heard interjecting into the conversation, attempting to cut short the interview. “Thank you so much. That’s really our time. I apologize,” the aide said.

“You can't do that to black media!” Charlamagne retored.

“I do that to white media and black media because my wife has to go on at 6 o’clock,” Biden shot back, apparently referring to a subsequent media appearance by Dr. Jill Biden, before adding: “Uh oh. I’m in trouble.”
